I, 28m, will be solo traveling to Hamburg for 4 days, Friday-Tuesday, this summer. I'm working on my itinerary. I have have all the major tourist stuff planned already, but I have a few questions:

1. Recommendations for nightlife; could be bars, clubs or something else, but places to go about and maybe meet similar aged people.

2. Recommendations for restaurants. I generally try to eat more local, but anywhere that you recommend for a sold meal. Can be casual.

3. I'm looking at trying to fit in a day trip, I'm looking at Luneburg. Is that reasonable given the time I am there? Is there another day trip you recommend?

Thanks!
